fuel tank removal ..ZZR11

[chameleon]

Do you turn the fuel tap Off? I know that sounds like a dumb question but the jap manual says to turn it "ON" which at first I did but fuel pissed out, as I would have expected? Now I m wondering if perhaps there is a problem with the other 50 hoses that come out of the fuel tap.

There should be a diaphram in the fuel tap that is opened by vacuum from a hose connected to one the carbs. If the diaphram is working properly, fuel cannot flow unless there is vacuum to the fuel tap.
ie sounds to me like either the diaphram is stuffed/removed or maybe one or more of the hoses are not connected to the correct connector on the fuel tap.
I always turn my fuel tap off before disconnecting any hoses.


Hope this helps

It sounds good neil, I'll check out the vaccum hose next time I run her up.

Ignore the manual. Turn the tap off. Whoever wrote the manual obviously thought the 1100 had a vacuum tap, which they don't. If the tap is a vacuum tap then there is no off position. only ON,RES and PRIME or PRI. ZZR1100 has an off position so it is not a vacuum tap. I always start it and run it for abour 30 seconds with the tap in the off position so you don't get a fuel dribble out of the hose when you pull it off. Or if you are going to do the valves and it needs to be stone cold (and it does) then just do the same the night before. If you are pulling the carbs off, run it for about 30 secs and then pull the hose off while it is still running and let it run dry (it'll take a couple of minutes) and you will just about drain the whole lot, carbs, hose and fuel pump. After you put it together you have to fill the carbs up, but you don't have to crank and crank it (the fuel pump only really works while motor is turning, don't ask me why) to get the bowls full again. Found this technique by accident. Put the bike in gear, leave the sidestand down and leave the clutch alone. Press the start button (put it up on the centrestand, just in case one of your switches doesn't work or has been disconnected (if they have, then bike will crawl forward and fall over)), you will hear a ticking as fuel pump fills up the carbs. When the ticking slows down to nothing the carbs are full, put it back in neutral and it should fire up first go.

Ok Goanna, sounds like you have the art form down pat. I'll print that out and stick it in the manual as a supplement I think Bloody Japo interpretors

So you do your own shims do you -
We will have to have a long chat one day soon if that is the case. I have this fear, a fear of mechanics, that a mechanic will "FU*K UP MY ENGINE" while it's in for a major. I'd much rather have the pleasure of doing it myself, with the aid of, and under the guiding eye of, an expert! For which i would be prepared to pay $$$
